Don’t shout at your JBOD, they don’t like it

Guy yells at his JBOD to prove vibration is an issue in disk latency.

So what do you do if you have a video camera, data center, and a foreign dude who may not have gone through puberty yet who likes to look at datacenter statistics? You make a video showing that if you yell at your JBOD, latency goes up.

These two guys have demonstrated proof that disk vibration is a significant factor to take into account on latency, at least in a JOBD. When the guy yells into the JBOD, the latency shoots up because of the vibration caused.

The part that's funny to me is that his shout is only marginally louder than the background noise in the data center. It's a funny illustration of the effects of vibration on latency. Just try to not laugh at the bloke as his voice cracks from the nerdgasm from finding a way to illustrate his findings.
